Digital video recorder with slot type mainboard

ABSTRACT

The present invention is related to a digital video recorder comprising a plurality of male slots, an image compression substrate including a plurality of channels, a female connector which is connected to one side of lower surface of image compression substrate, and inserted into one of a plurality of male slots, a male connector arranged on side surface of the female connector, and a female connector which is connected to the male connector and is formed on one side of lower surface of image compression substrate. Accordingly, in connection with the structure of the mainboard of the digital video recorder of the present invention, each function substrate can be included with only one substrate, and the present invention has the merit of assembling the product very easily by inserting the substrate into the slot. Besides, when the products are damaged or do not function, the products are repaired by replacing only the damaged substrate with a new one, and there is an effect that it is possible to use the products by replacing only the substrate with a new one when the products are upgraded or the functions are changed, and it is necessary to replace the substrate.

TECHNICAL FIELD

The present invention is related to a digital video recorder, in particular to a digital video recorder with slot type mainboard.

BACKGROUND ART

Generally, conventional digital video recorder was produced in the form of not slot type but on-board type substrate and has been assembled. Therefore, it was not possible to cope with the change of the number of channels rapidly. That is, there was a problem that according to the number of the channels required by the users, the new substrate of digital video recorder had to be manufactured. Conventional digital video recorder was generally produced with setting 4 channels as a basis. But, nowadays, as the functions of the digital video recorder are getting diversified, the case of the digital video recorder is increasing bit by bit while connecting the digital video recorder to various kinds of outside devices. So, since the number of the necessary channels is increasing, there was a difficulty in changing the number of the channels.

DISCLOSURE OF THE INVENTION

Accordingly, the present invention solves above-mentioned conventional technical problems, and the object of the present invention is to provide a digital video recorder which can increase the number of the channels for connection to the outside devices connected to the digital video recorder by the number of the channels required by the users.

The structure of the present invention for achieving above purpose is composed of a plurality of male slots, image compression substrate including a plurality of channels, female connector which is connected to one side of lower surface of image compression substrate, and inserted into one of a plurality of male slots, male connector arranged on the side surface of the female connector, and female connector which is connected to the male connector and is formed on one side of lower surface of image compression substrate.

BRIEF DESCRIPTION OF THE DRAWINGS

FIG. 1 shows a slanting view representing the connection relationships between slot mounted on mainboard of digital video recorder, and image compression substrate.

FIG. 2 shows a slanting view representing the connection relationships between digital video recorder, and image compression substrate mounted on mainboard.

EMBODIMENT OF THE INVENTION

The preferred embodiment will be described in detail with referring to the attached drawings.

FIG. 1 shows a slanting view representing the connection relationships between slot mounted on mainboard of digital video recorder (not shown), and image compression substrate.

As is shown, the image compression substrate is connected to one slot (2) of a plurality of slots (2) mounted on the mainboard. The connection relationships are will be described in detail. A male-female connector (5) is inserted between the slot (2), and a female connector (4) protruding from the lower part of one side of the image compression substrate (3), thereby connecting the slot (2) and the female connector (4). That is, the slot (2) is connected to the female connector of the male-female connector (5), and the female connector (4) of the image compression substrate (3) is connected to the male connector of male-female connector (5). Therefore, based upon the above-mentioned relationships, the image compression substrate (3) is connected to a plurality of slots mounted on the mainboard (1). The image compression substrate (3) will be explained in detail with referring to FIG. 1 and FIG. 2. 4 connection terminals (not shown) are arranged on one side of the image compression substrate (3). Accordingly, it can be connected to the outside devices (6) such as video camera and CCTV. Then, the image formed by combining the image input which is inputted through an image input terminal of the image compression substrate (3) from the outside devices (6) connected as described above is transmitted to the input of digital signal processor (not shown) and is compressed. Each of the compressed outside image input is transmitted to the mainboard (1) through slot (2) as the stream, respectively. So, in this way, depending upon how many the image compression substrate (3) is inserted into the mainboard (1), it is possible to produce digital video recorder having 4 channel, 8 channel or 12 channel.

The embodiment of the present invention is described only for the illustration, it is natural that the changes or the modifications can be made by a person having ordinary skill in the art to which the invention pertains if they are within the scope and true meanings of the present invention.

POSSIBILITY OF THE INDUSTRIAL APPLICATION

In connection with the structure of the mainboard of the digital video recorder of the present invention, each function substrate can be included with only one substrate, and the present invention has the merit of assembling the product very easily by inserting the substrate into the slot. Besides, when the products are damaged or do not function, the products are repaired by replacing only the damaged substrate with a new one, and there is an effect that it is possible to use the products by replacing only the substrate with a new one when the products are upgraded or the functions are changed, and it is necessary to replace the substrate.
